Category: ATX Power Supply

Every electronic circuit will work as good as its power supply. However this is often overlooked. There are two main families of power supplies: the linear power supply and switch mode power supplies. Linear power supplies are easier to manufacture and to troubleshoot. But they have the disadvantage (especially for high power), the circuit is more complicated with the results of less power and heat faster than the switch mode power supply. (more…)

The Current Source/Regulator circuit powers the load through the regulator's input rather than its output. Since the regulator's output sees constant dummy load R1, it attempts to consume a constant amount of current, regardless of what the voltage across the actual load really is. Therefore, the regulator's input works as a constant current source for the actual load. (more…)

The Korean manufacturer Zalman introduces two power supplies in its class HP PLUS, the ZM500-HP PLUS and ZM600-HP PLUS. 80Plus Bronze certified, they are characterized by a cooling system inspired by the original architecture of the CPU coolers. (more…)

Actually power supply repair is rarely - less expensive to replace it with new. A defective power supply is usually thrown away, unless, of course, it is not a quality or expensive. In the latter case it is better to send it to a firm that specializes in the repair of power units and other components. (more…)

The quality of power supply depends not only on power output. Experience shows that if a room is more than one computer and electrical network quality is low (often disappears voltage noise occurs, etc.), systems with powerful power supply systems work much better with low-cost units to be installed in some models of low-class .
